Failed resorption of bioabsorbable meniscus repair devices

Abstract

Bioabsorbable meniscus repair devices are being used more frequently because of their easy and quick application and reduced risk of neurovascular complications. Three cases, whose menisci were repaired with Biostinger bioabsorbable device and having remaining symptoms mimicking meniscus tear, are reported in this article. In the second-look arthroscopies of all three cases we observed, repaired menisci had healed and some of the repair devices had not been resorbed. Symptoms disappeared soon after removal of unresorbed materials. Late resorption of bioabsorbable meniscus material may cause intra-articular problems such as synovitis and chondral lesions. These problems should be addressed by meniscal implant designers and researchers.
